The afila bearing Filigreen pea variety was crossed with 12 varieties of normal leaf structure with the objective of evaluating the effect of afila genotype on pod formation. Genetic analysis of the F1 and F2 generation (3:1 ratio of normal leaves:afila respectively) confirmed the recessive monogenetic character of the property. The number of pods per plant in the F1 generation (normal leaf structure) was greater compared with both parent types. A smaller number of pods per plant (13) was reported for afila homozygous genotypes in the F2 compared with the F1 generation. However, compared with the normal leaved parents, the decrease was 1; while a 30 greater pea pod formation than in the afila parents was recorded. The decrease of the number of pods per plant in the F2 generation of afila genotypes was probably related to the smaller photosynthetic assimilation surface.
